AI Technical Summary

Problems solved by technology

Parallel channels were slow, bulky and nowadays rarely encountered.
This has sometimes been accomplished through the use of an additional test mainframe, which is typically complex and expensive to maintain.
The costs entailed by a mainframe computer are substantial, requiring numerous personnel and equipment.
Although there are existing standard channel programs, additional complexities arise in how custom channel programs are developed and executed on a host mainframe.
Unless a user is satisfied with using pre-existing utilities such as a copy routine, the user must develop channel programs using Assembler language which is fairly arcane and exceedingly complex when compared to higher level languages.

Abstract

A method and a system to emulate a mainframe data channel for testing and diagnostics of mainframe peripheral devices and for remote control and configuration of the testing and diagnostics. The system includes an emulator central processing unit communicably attached to at least one of the mainframe peripheral devices. First driver software is resident in the emulator central processing unit to initialize and start an adaptor for at least one mainframe peripheral device. Second channel program software is resident in the emulator central processing unit having commands to the emulator central processing unit and to the mainframe peripheral devices. Third application software is resident in the emulator central processing unit to test and diagnose the mainframe peripheral devices. Fourth software resident in the emulator central processing unit validates remote access to the emulator central processing unit.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention is directed to a process and a system to emulate a mainframe data channel for testing and diagnostics of mainframe peripheral devices. In particular, the present invention is directed to a device to emulate a mainframe channel which is self-contained and portable and permits testing and diagnostics of mainframe peripheral devices and permits remote control and configuration of the testing and diagnostics.[0003]2. Prior Art[0004]Mainframe channels are known, independent hardware and software components that coordinate input and output functions (I / O) between a mainframe central processing unit and a set of controllers or devices. Mainframe channels are used in computer systems, such as mainframes, that handle channel input / output operations independently of the computer system's central processing unit. A channel is an independent hardware and software component that coordinates all input and output...
